Abstract
An approach and a mechanism for the definition and maintenance of views within temporal database environments are outlined. The view definition language makes use of extending Boolean and comparison operators by allowing their operands to be sets of intervals. A mechanism for maintaining temporal views is presented, and it is shown that temporal database views have far fewer maintenance problems than their standard relational counterparts
